Bug 24580 – ImportC: Asm label after attributes results in syntax error

The following line can currently not be parsed by ImportC: ``` int ioctl(int __fd, unsigned __request, ...) __attribute__((overloadable)) __attribute__((enable_if(1, ""))) asm("ioctl"); ``` DMD prints the following error instead: ``` Error: `=`, `;` or `,` expected to end declaration instead of `asm` ``` The line is from an Android header: https://android.googlesource.com/platform/bionic/+/364fc76047989ef29100d52722cb7d918236cfd4/libc/include/bits/ioctl.h#60 The `asm` part is an asm label (https://clang.llvm.org/docs/AttributeReference.html#asm). ImportC can already parse all attributes and the asm label, but not in this order.
